MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document body and extracted URLs indicate a lure for free in-game items, specifically mentioning Coin Master and Roblox. The presence of an embedded URI pointing to a suspicious domain, coupled with a high ML classifier score, suggests malicious intent. While no scripts were directly extracted, the document's structure and content strongly imply it's designed to redirect users to potentially malicious sites for scams or further payload delivery.

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
